In a world divided between humans and hyper-intelligent, man-eating bears, Kureha attends an all-girls school and holds onto a simple wish—to spend the rest of her life with her classmate and soul mate, Sumika. But after a secret rendezvous ends in tragedy, Kureha vows to never back down on her love and put a bullet in any bear she meets.

As she plots her revenge, the bear-attack body count begins to rise and two strange girls transfer into Kureha’s class. She doesn’t know it yet, but the girls who call themselves Ginko and Lulu are actually criminal bears in disguise! As they try to win Kureha’s heart , an army of high school girls gears up to go to war with all of bear-kind and anyone else who stands up for love. At this rate, getting the yuri seal of approval from an interdimensional tribunal of cool, beautiful, sexy judges is going to be the least of their troubles.
